FIELD OF INVENTION

This invention is related to a circular pool table that incorporates the features of a rectangular pool table as specified by the Billiard Congress of America (BCA) and/or World Pool-Billiard Association (WPA). In particular, this invention relates to a circular pool table that comprises a circular cushion having a geometric shape of the cushion of a corresponding rectangular pool table in order to provide the player with the sense of playing on a rectangular pool table. The pool table further comprises a playing surface, rail, and a plurality of pockets that mimic the corresponding features of a rectangular pool table according to the BCA and/or WPA to further convey the experience of playing on a tournament-qualified rectangular pool table.

BACKGROUND

In an effort to popularize circular pool tables in professional tournaments as well as usage for recreational purposes, a circular pool table is disclosed that incorporates one or more features of a corresponding rectangular pool table as specified by the BCA and/or WPA. Recreational/tournament players accustomed to rectangular pool tables built to BCA/WPA standards, respectively, may play on the circular pool table of the present invention with minimal changes in the sensation associated with playing on a rectangular pool table.

Rectangular pool tables have been adopted by the BCA and/or WPA as standard equipment for pool tournaments. (See for instance, http://www.bca-pool.com, http://www.www.wpa-pool.com, and Billiard: The Official Rules & Records Book, 2005 Edition, the content of which are incorporated herein in their entireties.) A rectangular pool table comprises a rectangular playing surface bounded by a rail. The rail comprises a sub-rail of a particular profile that is used to mount a cushion, also referred to as a bumper, according to the BCA and/or WPA. The cushion is made of molded rubber and has a particular geometric shape, namely K-66, K-55, or L-shaped according to the particular type of rectangular pool table. The playing surface of the rectangular pool table comprises a slate with a specific thickness and flatness and includes a cloth whose property is also defined by the BCA and/or WPA. The rectangular pool table also has a plurality of pockets that receive the pool balls either directly or via the banks of the rectangular pool table, i.e., the cushions.

The rail of a rectangular pool table includes a sub-rail of a specific geometry. The rail width including the cushion is within a specific range of allowable dimensions as specified by the BCA and/or WPA. It includes a number of sights located at specific positions to assist the player when making bank-shots.

The cushion of a rectangular pool table deflects pool balls upon impact. The ball trajectory is a function of its speed and direction as well as the rail, cushion, and playing surface geometry and material including the cloth that covers the pool table. The cushion of a rectangular pool table is a molded rubber that includes a control fabric molded to the top and base area of the cushion and which mounts on the sub-rail of the rail that is made up of wood. The profile of the cushion is of a particular geometry as specified by the BCA and/or WPA. For the conventional rectangular pool tables, the triangular K-66 profile is used while on carom tables, the triangular K-55 profile is used. For snooker tables, either the triangular K-66 or L-shaped snooker cushion profile is utilized.

The playing surface of a rectangular pool table comprises a slate of a specific strength that is capable of maintaining a particular flatness and deflection when loaded. The slate is further supported by a wooden frame of a specific thickness. The playing surface, as well as certain areas of the rail, is covered by a special cloth of specific property.

Rectangular pool tables comprise both corner and side pockets. The pockets include pocket openings that are of specific dimensions and profiles. Pocket mouth, throat, vertical angle, shelf, drop point slate radius, horizontal cut angle, facing, and liner are among the attributes of a pocket that are unique to rectangular pool tables as specified by the BCA and/or WPA.

All these features are critical to a player who relies solely on his/her skills to win. Furthermore, a tournament pool player would rather not experience a new playing sensation from one table to another. Therefore, a circular pool table that purports to become as popular as the rectangular pool table should incorporate one or more features of a corresponding BCA and/or WPA-approved rectangular pool table as practicable.

Although various circular pool tables have been devised, none has incorporated the features of rectangular pool tables that are critical to providing the player the feel of playing on a rectangular pool table as in the present invention. For instance, the Ellingsberg patent, U.S. Pat. No. 6,371,861, discloses a bumper pocket billiard table that is circular and comprises at least one adjustable bumper post positioned on the playing surface adjacent to but spaced apart by a selected dimension from the lip edge of an associated pocket opening. The Howell patent, U.S. Pat. No. 4,610,450, discloses a circular pool table having a plurality of pockets equally spaced around the table with the pocket opening spaced radially inward from the perimeter of the table. The Meyers et al. patent, U.S. Pat. No. 3,700,235 discloses a circular pool table having a number of pockets equally spaced around a circular bumper which includes one or more flat bumpers that project inwards toward the center of the table. The Chasley patent, U.S. Pat. No. 296,677 discloses a circular pool table comprising a circular rail and cushion secured to the edge of the table that are vertically adjustable to conform to various sizes of balls.

Circular pool tables do not have the popularity of rectangular pool tables. The BCA and WPA have well-defined specifications for standard rectangular pool tables, in particular those that will be utilized in billiard tournaments. In an attempt to popularize the circular pool table, one or more of the features critical to a player familiar with rectangular pool tables have been incorporated in the circular pool table of the present invention.

The playing surface 112 is bounded by the rail assembly 102 of a diameter 110 around its perimeter and may be supported via legs in various manners. In one preferred embodiment the playing surface comprises a slate that is supported via a slate support, cabinet, and leg assembled similar to a rectangular pool table. (See for instance, http://www.bestbilliard.com/resources/buildtable/cutout.cfm.) The playing surface 112, cushion 104, and certain areas of the rail assembly 102 are covered by a cloth 324 (see FIG. 3). In one preferred embodiment, the circular pool table 100 may further comprise one or more pockets 108 and one or more inwardly projecting cushions 106. It should be clear to a skilled artisan that although the present embodiments refer to a circular playing surface, other non-circular playing surfaces such as oval or octagonal playing surfaces are within the scope of the circular pool table of the present invention. It is contemplated that incorporating a BCA and/or WPA standard cushion in the circular pool table provides the same feel as playing on a rectangular pool table as the player executes shots causing the balls to contact the cushion and travel over the playing surface to the pockets.

FIG. 2 depicts a schematic diagram of a preferred embodiment of a cushion 200 which is made from the conventional triangular shape rubber cushion molded with the conventional K-66 profile as specified by the BCA and/or WPA. The K-66 profile has a nose height 202 and base 204 equal to one (1) inch and one and three sixteenth (1 3/16) inches, respectively, as specified by the BCA and/or WPA. The cushion 200 further comprises a control fabric (not shown but known to skilled artisans) molded to the top and base area of the cushion 200. In one embodiment, the cushion 200 is made from the conventional triangular shape rubber cushion with the conventional K-55 profile, such as that used for carom pool tables, and in another embodiment, the cushion 200 is made form the conventional L-shaped profile, referred to as snooker cushion, such as that used for snooker tables.

The cushion 200 is glued or otherwise attached to a sub-rail 400 (see FIG. 4) of the rail assembly 102 (discussed in more detail below), and is covered by the cloth 324 (discussed in more detail below), providing a cushion height 328 (see FIG. 3) equal to the cushion height, also referred to as the rail height, of a rectangular pool table as specified by the BCA and/or WPA. In one embodiment, the cushion height 328 (nose-line to table-bed) is sixty three and one half percent (63½%) or between sixty two and one half percent (62½%) and sixty four and one half percent (64½%) of the diameter of a standard BCA and/or WPA billiard ball. The cushion 200 when glued to the sub-rail 400 of the rail assembly 102 and covered by the cloth 324 provides a width 326 (see FIG. 3) equal to the cushion width of a rectangular pool table as specified by the BCA and/or WPA.
